[0026] In related technologies, the flip-up TV 10 can be used in some narrow environments, such as train carriages or vehicle compartments. In these relatively narrow environments, the flip-up TV 10 can be installed on the ceiling of the carriage, and the display screen 100 can be flipped and folded to hide in the ceiling of the carriage, so as not to occupy the space of the train passage and not to hinder the movement of people.

[0027] Furthermore, the carriage can supply power to the flip-up television 10. In some cases, if a circuit failure occurs in the carriage, the display screen 100 may automatically turn on, which could pose a certain safety hazard to personnel. Therefore, this application proposes a flip-up television 10.

[0028] Please refer to Figure 1In some embodiments, the flip-up television 10 is installed on the ceiling of a vehicle interior, specifically a train, such as a regular train, bullet train, or high-speed train, or a car or electric car. The flip-up television 10 includes a display screen 100, a base 200, a connector 300, and a de-energized electromagnet 400. The display screen 100 includes a magnetic component 110, which specifically refers to a substance with magnetic materials, such as the three metallic elements iron, cobalt, and nickel, as well as alloys (such as steel, cast iron, permalloy, etc.) and some oxides (such as magnetite). Alternatively, the magnetic component 110 can also be a permanent magnet, and when the magnetic component 110 is a permanent magnet, its polarity is opposite to the polarity exhibited by the de-energized electromagnet 400 when it is de-energized. The base 200 is provided with a receiving groove 210, and the base 200 can be installed on the ceiling of a vehicle interior, such as the ceiling of a train carriage or the interior surface of a car. One end of the connector 300 is rotatably connected to the base 200, and the other end is fixedly connected to the display screen 100. The connector 300 allows the display screen 100 to flip. The size of the display screen 100 can be 5.6 inches, 7 inches, 8 inches, 10.1 inches, 15 inches, 15.6 inches, 17 inches, or 19 inches. The display screen 100 has a working state and a retracted state. When the display screen 100 is in the retracted state, it is located in the receiving slot 210, as detailed in [reference needed]. Figure 3 When the display screen 100 is in working condition, the display screen 100 leaves the receiving slot 210. (See reference [link to relevant documentation] for details.) Figure 4 In other words, flipping the display screen 100 allows for convenient viewing of videos or easy storage. A de-energized electromagnet 400 is housed in the receiving slot 210. When power is off, the electromagnet 400 attracts the magnetic component 110, keeping the display screen 100 in a stored state. Specifically, the display screen 100 has an operating state and a stored state. When in the operating state, the display screen 100 can be opened from the receiving slot 210 for convenient video viewing. When in the stored state, the display screen 100 is located in the receiving slot 210, which does not occupy interior space. In the event of a circuit failure and power outage, the de-energized electromagnet 400, being magnetic after power loss, can attract the magnetic component 110, preventing the display screen 100 from opening and keeping it in a stored state. In essence, the flip-up television 10 offers a high level of safety.

[0029] To further explain, the working principle of the power-off electromagnet 400 is that it relies on a built-in permanent magnet to maintain attraction when power is off. When power is on, the electromagnetic field and the magnetic field of the permanent magnet have opposite polarities, thus canceling out the attraction. That is, when a circuit fault occurs and power is off, the power-off electromagnet 400 actually has magnetic force, which can attract the magnetic component 110, keeping the display screen 100 in the receiving slot 210. Without the power-off electromagnet 400, since the display screen 100 is located on the ceiling inside the vehicle, it may flip over under gravity and become operational, occupying space and potentially colliding with a person's head. In addition to the effects of gravity, the display screen 100 may also open due to the inertia of the vehicle, creating a safety hazard. Specifically, the cooperation between the power-off electromagnet 400 and the magnetic component 110 effectively improves the safety of the flip-up television 10.

[0030] Furthermore, the following describes how to switch the display screen 100 between its stored and working states. For details, please refer to [link / reference]. Figure 2 In some embodiments, the flip-up TV 10 further includes a hinge 500 and a drive component 600. The hinge 500 is fixedly connected to the connector 300, and the drive component 600 is connected to the hinge 500, used to drive the hinge 500 to rotate. The drive component 600 can be a motor; after the motor is connected to the hinge 500, it can drive the hinge 500 to rotate. When the hinge 500 rotates, it can drive the connector 300 to rotate, which in turn drives the display screen 100 to rotate, thus switching the display screen 100 between a retracted state and a working state. Furthermore, the hinge 500 can be made of metal, such as stainless steel or iron. The structure where the hinge 500 rotates and ultimately drives the display screen 100 to flip is simple and has low economic cost. In some embodiments, to make the rotation of the hinge 500 smoother, a bearing housing can be mounted on the base 200, and a bearing can be installed on the hinge 500.

[0031] Furthermore, to enhance the safety of the flip-screen TV 10, an electromagnetic power-off brake 700 can be installed. That is, please refer to... Figure 2In some embodiments, the flip-up television 10 also includes an electromagnetic power-off brake 700. The electromagnetic power-off brake 700 is connected to the rotating shaft 500 and can brake the rotating shaft 500 when power is off. Specifically, the electromagnetic power-off brake 700 adopts the working principle of energized disengagement and de-energized braking. Electromagnetic force counteracts spring pressure to separate the friction disc (in the energized state), and after power is off, the spring resets to generate braking torque. Thus, when power is off, the electromagnetic power-off brake 700 can effectively prevent the rotating shaft 500 from rotating, thereby further preventing the display screen 100 from flipping. The electromagnetic power-off brake 700 can be mounted on the base 200 and then connected to the rotating shaft 500.

[0032] Further, please refer to Figure 2 In some embodiments, the flip-up television 10 also includes a planetary reducer 800, and the drive component 600 is configured as a motor, which is connected to the rotating shaft 500 via the planetary reducer 800. The planetary reducer 800 is a precision mechanical device based on the principle of planetary gear transmission, consisting of four main components: a sun gear, planet gears, an internal gear ring, and a planet carrier. Its working process involves the sun gear receiving high-speed power from a prime mover such as a motor and rotating it, which in turn drives the surrounding planet gears to revolve around the sun gear while rotating on their own axes. The power is then transmitted through the planet carrier, ultimately converting the input high-speed rotation into low-speed motion while significantly increasing the output torque. In other words, the core function of the planetary reducer 800 is to convert the high-speed rotation of a prime mover such as a motor into low-speed motion while significantly increasing the output torque. In other words, by using a motor in conjunction with the planetary gear reducer, the torque of the rotating shaft 500 can be amplified, and the rotational speed of the rotating shaft 500 can be reduced. Thus, the flip-up television 10 can achieve the flipping of the display screen 100 using a small motor. The small motor takes up little space, which reduces the overall size of the flip TV 10 and effectively prevents it from taking up too much space in the vehicle.

[0033] Further, please refer to Figure 2 In some embodiments, the flip-screen TV 10 also includes an angle sensor 900. The angle sensor 900 is used to detect the rotation angle of the pivot 500. Specifically, the angle sensor 900 has multiple functions. For example, the angle sensor 900 can feed back the detected angle signal to the control system, which adjusts the motor speed according to a preset target value, thereby enabling the motor to precisely control the flip-screen display 100 to flip. For instance, when the angle sensor 900 detects the rotation angle of the pivot 500, if the detected angle exceeds a safety threshold, the angle sensor 900 can send a signal to the control system, which then issues an alarm or emergency stop command, effectively preventing damage to the flip-screen TV 10.

[0034] Further, please refer to Figure 2In some embodiments, the flip-up television 10 further includes a coupling 1000, with its two ends connected to the rotating shaft 500 and the angle sensor 900, respectively. Specifically, after the two ends of the coupling 1000 are connected to the rotating shaft 500 and the angle sensor 900, the coupling 1000 can establish a reliable mechanical linkage between the rotating shaft 500 and the angle sensor 900, enabling the angle sensor 900 to accurately detect parameters such as the angle and rotation speed of the rotating shaft 500, while ensuring the stability and safety of the angle sensor 900's detection process.

[0035] Further, please refer to Figure 1 In some embodiments, the de-energized electromagnet 400 is disposed on the bottom wall of the receiving groove 210. The display screen 100 includes a magnetic element 110 and a body 120, with the magnetic element 110 disposed on the side of the body 120 facing the bottom wall of the receiving groove 210. Specifically, the bottom wall of the receiving groove 210 refers to the wall surface opposite to the opening of the receiving groove 210. The de-energized electromagnet 400 is disposed behind the bottom wall of the receiving groove 210, and the bottom wall space of the receiving groove 210 is relatively large, which provides ample space for the de-energized electromagnet 400 to be placed.

[0036] Furthermore, the de-energized electromagnet 400 can have other installation positions besides those described above. Specifically, in some embodiments, the de-energized electromagnet 400 is installed on the side wall of the receiving groove 210. The display screen 100 includes a magnetic element 110 and a body 120, with the magnetic element 110 installed on the side of the body 120. The de-energized electromagnet 400 being installed on the side wall of the receiving groove 210, and the magnetic element 110 being installed on the side of the body 120, provides more space on the front of the body 120, allowing for a larger LCD screen size and a smaller bezel in the display screen 100. This further enhances the viewing experience of the flip TV 10.

[0037] Furthermore, in some embodiments, multiple de-energized electromagnets 400 and magnetic components 110 are provided, with each de-energized electromagnet 400 and one magnetic component 110 correspondingly arranged. Specifically, there may be two, three, four, five, etc., de-energized electromagnets 400, and there may also be two, three, four, five, etc., magnetic components 110. The arrangement of multiple de-energized electromagnets 400 and magnetic components 110 can further improve the safety of the flip-up television 10. When there are two de-energized electromagnets 400, the two de-energized electromagnets 400 are located at both ends of the receiving groove 210, and when there are three de-energized electromagnets 400, the three de-energized electromagnets 400 can be arranged in a triangular arrangement. When there are two magnetic components 110, the two magnetic components 110 are located at both ends of the body 120, and when there are three magnetic components 110, the three magnetic components 110 can be arranged in a triangular arrangement.

[0038] In some embodiments, the vehicle includes the flip-up television 10 of any of the above embodiments. Specifically, the display screen 100 has an operating state and a retracted state. When the display screen 100 is in the operating state, it can be opened from the receiving slot 210 for convenient video viewing. When the display screen 100 is in the retracted state, it is located in the receiving slot 210, which does not occupy interior space. In the event of a circuit failure and power outage, the de-energized electromagnet 400, after being de-energized, retains its magnetism and can attract the magnetic component 110, thereby preventing the display screen 100 from opening and keeping it in the retracted state. Specifically, the flip-up television 10 offers high safety. Furthermore, vehicles equipped with this flip-up television 10 have higher safety.

[0039] It should be added that the specific means of transportation can be cars, SUVs, buses, trucks, electric vehicles, high-speed trains, bullet trains, subways, light rail, maglev trains, cruise ships, ferries, container ships, tankers, passenger planes, cargo planes, helicopters, business jets, etc. All of the above-listed means of transportation can be equipped with a flip-up TV 10.

[0040] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
